Hello everyone, I am trying to connect my PLC to Ignition, but I get the error message below. My Ignition Designer is in a VM, and I can ping the PLC IP address from that VM. Does anyone have information on how to resolve this? Thank you! ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/a/4/a425cada11a8595218e850e3ad7cff0a04cdf823.png) ---

The gateway makes the connection to the PLC, not the designer. - Can you ping from the gateway to the PLC? - What firmware is in the PLC? (If \>20, you are using the wrong driver.) ---

Hi, I am facing the same kind of issue. **Connecting : Protocol: EIP - Run Mode.** Could you please help me understand what this means and suggest a solution? ---

This is a question about your logix version. What version of RSLogix and/or Studio are you using? Depending on this, you will want to change which driver version you apply. Rockwell changed their driver interface around the 20/21 version split. ---

I'm currently using studio 5000 V32.01 And my plc is 5380 compact logix (5069-L330ER) ---

Perfect. Make sure you are connecting using this driver: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/b/0/b0fb8735ef0f4a0e03666a1cf89aa925864f4b84.png) ---

Download mode means some engineer or technician is messing with the PLC program. ---

oh wow...no one should have access to the PLC. ---

If the PLC is power cycled, it might show that briefly before the program is initialized. ---

we upgraded from v7.9 to v8.3 and had issues, so then we went to v3.1 and that is where we are at now. The version upgrade was a year ago and then we went down for a water tank maintenance project. When we came back online, that is when I started getting the issue i described earlier ...i have not cycled power to the PLC. ---

Awesome, that gives me an area where i can go and start troubleshooting. sounds like it is a wiring/power issue, not a gateway issue. ---

Is it stuck in download mode? Are you sure the PLC didn't lose its program after a power cycle? (Bad battery on old CPU, perhaps?) ---

i can see the PLC in RSLinx and i can go online in my laptop, but in one of our machines that is a client that has RSlinx and RSLogix 5000 in it, i lose connection when ever Ignition loses comms. so it comes and goes. it is only that one PLC. ![1](https://us1.discourse-cdn.com/inductiveautomation/original/3X/c/e/ceec9d0f1691edb3ed9507a0dfff3824bc090fa5.jpeg) ![2](https://us1.discourse-cdn.com/inductiveautomation/original/3X/c/e/ceec9d0f1691edb3ed9507a0dfff3824bc090fa5.jpeg) ---

> [@Enrique\_Torres](#): > > RSLogix 5000 in it, i lose connection when ever Ignition loses comms Then it is a problem in your network or in the hardware, not in Ignition. ---

i just thought since i can see it through my laptop i thought maybe it was in the Gateway. Awesome, thank you sir for your help, greatly appreciate 🤘
